Linearization
Compensates for non-linear output of the belt scale caused by varying load rates.
Load Cell
Strain Gauge type transducer that produces an electrical output proportional to force
(load) applied.
LVDT
An electromechanical transducer that produces an electrical output proportional to the
displacement of a separate movable core.
mA
A unit of measure for current flow, milliamperes.
Material Test
Material samples used to verify the accuracy of the span calibration.
Modbus
An industry standard protocol used by popular SCADA and HMI systems.
Moisture sensor
A mA input function to incorporate moisture reading from an external moisture sensor
Multispan
Since every material has its own unique physical properties, and may impact differently, a
span calibration is required for each material to realize maximum accuracy.
PID
Proportional Integral Derivative control is used to control the feed rate to a setpoint,
either internal to the BW500 or external.
RAM
Random Access Memory.
Random Access Memory
Memory that has both read and write capabilities.
Relay
An electromechanical device with contacts that can be closed or opened by energizing a
coil.
Routine Span
Any operator initiated span calibration.
Routine Zero
Any operator initiated zero calibration.
Setpoint
A value that the integrator is trying to match.
SmartLinx
An interface to popular industrial communication systems.
SPA
Single Parameter Access, used to view or edit parameters through the available
communication ports.
